Title: Improvements in or relating to machines for folding serviettes, handkerchiefs and like articles
IPC: D06F89/00
Filed: 1950-05-04
Abstract: 697,011. Folding piece goods. TURNER, C. E., and WESTON LAUNDRY MACHINE CO., Ltd. June 27, 1951. [May 4, 1950] No. 11037/50. Class 42 (ii). A machine for folding serviettes, handkerchiefs and like articles comprises a table 2 upon which the article 6 is placed in flat condition, primary folding bars or members 4 which are adapted to move in a vertical plane and effect a primary folding by guiding the article through an elongated opening 3 in the table and co-act with a normally stationary, but adjustable, vertical folding bar or member 5 to fold the article and locate it between aligned movable secondary folding members or blades 10 and a normally stationary but adjustable secondary folding member or blade 11, the secondary folding members being disposed in a vertical plane at right angles to that of the primary folding members. After the secondary folding, pressure rollers 14 are moved automatically to protrude through slots 48 in the walls 49, engage the folded article and feed it through an ejection . slot or to a conveyer which delivers it to one side of the machine. The rollers 14, and auxiliary rollers 50 are preferably rotated continuously. The bar 5 and each of the bars 4 consists of two parts separated by a gap, to allow the bars 10 and article 6 to pass therethrough. The movements of the folding bars 4 and 10 and of the members carrying the'rollers 14 are caused by cams on a shaft 16, acting through linkages on the said members to cause a complete cycle of operations for each rotation of the shaft 16 ; the latter is driven from a shaft 80 through a clutch 83 controlled by a pedal 88, mechanism associated with the shaft 16 preventing the clutch from being disengaged until a revolution of the shaft 16 has been completed. The positions of the adjustable primary and secondary folding blades 5 and 11 are controlled by an external hand lever or wheel on a shaft 62, which acts through linkages on these members, and on width-indicating guides 60 slidable over the table 2.

Cylinder 16 of the oleo leg is formed with a slotted guide 21 in which is slidable a block 22 universally attached at one end of a strut 25. Block 22 is also universally attached to the ram of a hydraulic jack 30. The wheel is retracted in a fore-and-aft plane and also movable radially as indicated in Fig. 1, to this end the upper ends of cylinder 16, strut 12, strut 25, and jack cylinder 30 are connected to the wing structure by universal pivots. In a further modification of the undercarriage described in the parent Specification, Fig. 4, cylinder 35 of a wheel-carrying leg adapted for lateral retraction is braced in the fore-and-aft plane by a strut 48.
